COLLAR-FASTENER. v

7 Specification of Letters Patent.

Application filed 'February 19, 1920. Qerlal No. 859,778.

To all 'whomit may concern:

Be it known that I, FRANK HYDE, a c1t1- zen of the United States, residing at Sioux Falls, in the county of Minnehaha and State of South Dakota, have invented certain new and useful Improvements in Collar-Fasteners, of which the following its a specification.

This invention relates to certain new and useful improvements in collar fasteners and the primary object thereof is to provide a fastener which is sprin tensioned so as to maintain the collar on s or points under constant tension and still allow same, to yield for any reason incident to collar wear.

A further object of the invention is to provide a spring tensioned collar fastener in which the spring is practically concealed and wherein the contractile movement of the two .hooks or collar engaging elements is restricted to a predetermined extent.

Still further theinvention aims to provide a collar fastener wherein both hooks are tensioned by a single spring and where in the structure is simple and economical and possessed of a minimum of parts.

In the drawings:

Figure 1, is a top plan view of the invention;

Fig. 2 is a front elevation;

Fig. 3 is a rear elevation; and

Fig. 4 is an enlarged section on line 44 of Fig. 1.

In proceeding in accordance with the present invention a pair of substantially similar members are employed each having a collar engaging hook or pin point '1, formed upon the outer end of a shank 2. The shanks are of substantially rectangular cross-section and having their inner ends turned at right angles at 3 and formed with eyes corresponding to that of the cross-sections of the shanks to slidably receive and prevent rotation of the latter.

Each shank is bent or ofiset adjacent its hook 'or pin point to form a shoulder or stop 4 whlch engages the adjacent eye member 'to restrict contractile movement of the members under the influence of the coil spring 5. Asingle spring is employed which abuts the eye members at its ends and which lies to the rear of the foremost shank, being practically concealed by the latter. Thus the device presents an attractive appearance, and is simple and economical, involving but three parts in its entirety.

It will also be noted hooks present a symmetrical appearance regardless of any position to which the mem-. bers may be adjusted and that the whole presents an artistic and ornamentalappearance which is a commercial requirement to successful sale of articles of this kind.

It will further be noted that the stops 4 are located so as to leave the pinpoints free for engaging, the collar ends, or in other words are spaced from the pin points so as to not permit the eyes to obstruct or interfere with free engagement of the points with the collar ends.

What is claimed is In a collar fastener, a pair of substantially similar members each having a shank with a pin point on the outer end of the shank, the shanks being of substantially rectangular cross section and having their inner ends turned at right angles and formed with eyes which conformably and slidably receive the shank of the opposite member, and a single coil spring to the rear of one shank and engaged over the other shank and between the eyes, each shank being offset adjacent its pin point to form a stop engaging the eye of the opposite shank to restrict contractile movement of the shanks the front shank being offset rearwardly an the rear shank being offset forwardly to bring the shanks into alinement.

In testimony whereof I afiix my signature.
